Recently looked at a very nice used one, but need advice on what it is worth.

An "upgraded Mirage" 12 gauge with a full set of (3)Briley skeet tubes and aftermarket (nice) engraving. Restocked very well with deluxe wood. Has 25+ choke tubes in the various gauges. Not sure of the age, but everything seems tight. I'd have a gunsmith validate before finalizing the purchase.
